Hedychium plant named ‘Tahitian Flame’

ABSTRACT

A new and distinct cultivar of  Hedychium  plant characterized by striking, strongly variegated leaves, showy fragrant flowers, repeat blooming, and excellent vigor.

Botanical denomination: Hedychium spp.

Variety designation: ‘Tahitian Flame’.

Parentage: Hedychium (flavum×coccineum), ‘Doctor Moy’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of an herbaceous perennial of the genus, Hedychium, and known by the cultivar name of ‘Tahitian Flame’. The genus Hedychium is a member of the family Zingiberaceae. This cultivar occurred as natural branch mutation of Hedychium ‘Doctor Moy’ (an unpatented plant) in a greenhouse in Canby, Oreg. Hedychium ‘Doctor Moy’ was bred by retired plant breeder Dr. Moy and is an interspecific hybrid between Hedychium. flavum and Hedychium. coccineum. The new cultivar differs from its parent in having stronger variegation.

SUMMARY OF THE INVENTION

This new cultivar is unique due to its strong, striking, streaked variegation. This variegation is a great improvement over the parent, Hedychium ‘Doctor Moy’, as the streaking is much wider and brighter. In addition this new cultivar has showy fragrant flowers, repeat blooming, and excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the parent plant. Asexual propagation by tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

Comparison to Hedychium ‘Doctor Moy’

Hedychium ‘Doctor Moy’ (unpatented) is admired for its repeat blooming, long lasting blooms, showy flowers, its upright, non-falling habit, its sweet fragrance, and its unique variegation. Dr. Ying Doon Moy describes his plant as “Medium height plant has a large strong stem (peudostem), the distance between the leaves on the psuedostems are shorter, so the leaves of this variety has density. It has a special character in its shorter but broader leaves that is the green leaves having some light yellow stripes or spots in it. The orange flowers are fragrant and lovely.”

Hedychium ‘Tahitian Flame’ has all these characteristics and much stronger, wider, and brighter variegation.
